The Exploring Between Soil Particle Size And Magnetic Susceptibility Of Zhong Liang Mountain Beibei, Chong Qing

Granularity has been making a great achivement as an indicator on the research of climate change.Sedimetary grain size is the percentage of different size of particles in sediment.It is useful for us to figure out the Material source,handing media,power and sedimentary environment.lt is one of the most important features of the sediment,and has played a decision role on environment analysis and reconstruction.So far as we know,magnetic susceptibility has been applying in sediment environment and the climate of Northern China.At preseat,the global environment and climat change has become a relevant focus of world attention.In short,today is the key to understand tne past and pretict the future.As the above proposing questions,the paper try to start make some research about the relationship between the grain size and the magnetic susceptibility on three different soil profiles.Firstly,The experimental analysis of particle size shows that silt content is the most of the three different soil profiles, the following is clay content,and the last is the sand content.Accroding to the Diagram triamgle of grain size figure,we know that the three of all are clayey silt soil;Secondly, the number of transitional Stable single domain particles and Super-paramagnetic susceptibility particles which are reflected by Frequency dependent susceptibility is not the same on the three profiles,and it also can indicate the degree of soil weathering,illustrating that the yellow soil is the best,and the purple soil is the worst among the three.Besides,the result proved that John.Dilin's figure about different samples'main domain and the source of magnetic minerals showed they are formed by the weathering of parent material;Thirdly, correlation analysis showed that there were siginificantly negative relations between Frequency dependent susceptibility,Magnetic susceptibility and Standard deviation, Skewness in yellow soil.There were siginificantly positive relation between magnetic susceptibility and sand content in purple soil;Last,after the above analysis,we know that Magnetic susceptibility,Frequency development susceptibility in yellow soil,and Magnetic susceptibility in purple siol could measure up the climate changes in Southern China.
